From 1d048afe7e52462d6b2a31dd6ee09c4475f39b4b Mon Sep 17 00:00:00 2001 From: Christian Hewitt Date: Wed, 27 Jan 2021 19:40:47 +0000 Subject: drm/lima: add governor data with pre-defined thresholds This patch adapts the panfrost pre-defined thresholds change [0] to the lima driver to improve real-world performance. The upthreshold value has been set to ramp GPU frequency to max freq faster (compared to panfrost) to compensate for the lower overall performance of utgard devices.
